I don’t want her to think I’m a sleazy guy
This is a limiting mindset you should work to change. It's also a very normal one to have. You want to have enough social intelligence to know when you are stepping too far out of line, but unfortunately that concern that we have can sometimes impede our approaches or even let us talk ourselves out of approaching.
Instead of saying to yourself "I don’t want her to think I’m a sleazy guy" you should be saying to yourself "There is no reason why I am not enough" or "I am going to make this girl's night"
Remember, girls love to socialize. They enjoy when a guy walks up to them and they have a nice interaction. The more you do it, the nicer it will be. Just work on your mindset when approaching. Take 2-3 deep breaths before you go, every exhale eliminates the limiting belief, every inhale fills you with confidence and good vibes.
